Energy Grants & Subsidies in Belgium

Reduced VAT for Green Energy Works (2025)

In Belgium, the reduced VAT rate of 6% for the installation of solar panels and solar water heaters ended on 31 December 2024. From 2025, the installation of solar panels and solar water heaters in new builds is now subject to the standard VAT rate of 21%. However, heat pump installations in buildings over 10 years old can still benefit from the reduced VAT rate of 6%.

For green energy projects, regional grants and subsidies remain available. Visit the specific pages to explore the aid options tailored to your region.

Significant Changes Across Regions

Grants and subsidies for solar panels vary depending on the region in Belgium. In 2025, each region (Wallonia, Brussels, and Flanders) offers different schemes, making it essential to research the available options in your area to maximise financial benefits.

Regional Comparison :

Brussels

Brussels offers several schemes, including green certificates, RENOLUTION grants, and the Ecoreno Loan to improve energy efficiency. The solar panel compensation system has been replaced by an injection tariff, encouraging self-consumption.

Flanders

The Fluvius grant was discontinued in January 2024, but schemes such as the injection tariff, MijnVerbouwLening, and local subsidies are still available to support green energy projects, with retroactive grants for recent installations.

Wallonia

Since January 2024, Wallonia has discontinued grants for the installation of solar panels. However, schemes such as the Rénoprêt, the Housing Grants Package, and small works subsidies remain available, providing funding for energy renovation projects.

Even Without Direct Grants, Installing Solar Panels in Belgium Is Still a Wise Investment

Not only do you benefit from self-consumption to reduce your energy costs, but you also increase the value of your property. Furthermore, with the evolution of regional aid schemes and compensation systems, the accessibility of solar panels has improved, making this investment even more attractive.

questions? FAQs

Brussels: When Can I Apply for RENOLUTION Grants?

Applications for RENOLUTION Grants must be submitted within 12 months of receiving the final invoice for the works. If you used multiple companies for your renovations, each application can be submitted separately based on the invoice date of each contractor. However, it’s important to note that a grant can only be requested once for the same works and only once every 10 years.

Flanders: How Do I Apply for the Renovation Loan "Mijn VerbouwLening"?

To obtain the renovation loan in Flanders, start by contacting an "Energiehuis" centre in your municipality. The Flemish Energy Agency will then decide whether to approve your application. Ensure that: Your house was connected to the network before 1 January 2014, the building permit is more than 5 years old, the property meets the criteria of the EPC certificate.

Wallonia: Are Photovoltaic Grants Still Available in 2025?

If you’re considering installing solar panels this year, it’s important to know that photovoltaic grants previously available in Wallonia are no longer offered. 

Until 31 December 2023, certain incentives were in place in the region. These were intended to encourage Walloon residents to invest in a more ecological lifestyle through renewable energy. For example, the Prosumer tariff or the reversed metering system were available before this date.
